Ultramid A3X2G5為PA66級，采用25%玻璃纖維增強。是一種基于紅磷的阻燃等級。具有良好的電氣性能、彈性性能、高尺寸穩定性、高蠕變強度和良好的滑動摩擦性能。在低溫下提供良好的韌性、硬度、高剛度、高機械強度、剛度、熱穩定性、非常好的沖擊強度和良好的加工性。對化學品、熱潤滑劑和熱水、燃料、液壓流體和冷卻劑、制冷劑、染料、油漆、清潔劑、脫脂劑、脂肪族和芳香族碳氫化合物以及許多其他溶劑具有良好的抵抗力。與許多無定形塑料相比，它抗腐蝕、耐鹽和堿的水溶液以及應力裂紋形成。通過注塑加工并用于電氣應用。符合歐盟1907/2006號法規（REACH）、RohS指令2011/65/EC和WEEE指令2002/96/EC。

Ultramid A3X2G5 is a PA66 grade reinforced with 25% glass fiber. Is a flame retardant grade based on red phosphorus. Possesses good electrical properties, elastic properties, high dimensional stability, high creep strength and excellent sliding friction properties. Provides good toughness at low temperatures, hardness, high rigidity, high mechanical strength, stiffness, thermal stability, very good impact strength and good processability. Exhibits outstanding resistance to chemicals, hot lubricants and hot water, fuels, hydraulic fluids and coolants, refrigerants, dyes, paints, cleaners, degreasing agents, aliphatic and aromatic hydrocarbons and many other solvents. Is resistant to corrosion, to aqueous solutions of salts and alkalis and to stress-crack formation compared to many amorphous plastics. Processed by injection molding and used in electrical applications. Is compliant with EC Regulation 1907/2006 (REACH), RohS directive 2011/65/EC and WEEE directive 2002/96/EC.
